York Chiller

[INDIAN HEAD]

I have a york ycag36 46 d recip chiller. When it tries to start code f1 shows up for circuit 1. Circuit 2 starts and runs. F1 has several causes,low or high motor current, ext high pressure switch, micro high press sw. All are within range. Any suggestions ?

[Dr._Fleck]

faulty pressure switch?.. Maybe?

[INDIAN HEAD]

No external pressure switch and transducer shows same pressure as the compound guages on micro processor display

If the compressor is not starting and comes up F1 then the fault is caused by low(or no)current.Check the compressor fuses and check the contactor internals.
